Zusammenfassung:	Provided is a device, which includes a protection circuit electrically coupled to first and second voltage domains. The protection circuit includes a first silicon-controlled rectifier (SCR) and a second SCR connected in an anti-parallel configuration. The first SCR is configured to couple the first voltage domain and the second voltage domain based on the detection of the first triggering condition. The second SCR is configured to couple the second voltage domain and the first voltage domain based on the detection of the second triggering condition. The protection circuit is configured to isolate the first and second voltage domains in the absence of triggering conditions. 장치는 제1 및 제2 전압 도메인들에 전기적으로 연결되는 보호 회로를 포함한다. 보호 회로는 역병렬 구성(anti-parallel configuration)으로 연결되는 제1 실리콘-제어 정류기(SCR, silicon-controlled rectifier) 및 제2 SCR을 포함한다. 제1 SCR은 제1 트리거링 조건의 검출에 기초하여 제1 전압 도메인과 제2 전압 도메인을 연결하도록 구성된다. 제2 SCR은 제2 트리거링 조건의 검출에 기초하여 제2 전압 도메인과 제1 전압 도메인을 연결하도록 구성된다. 보호 회로는 트리거링 조건들이 없으면 제1 및 제2 전압 도메인들을 절연시키도록 구성된다.
